Circuit breakers are some of the most important components of any electrical system. They are designed to protect those systems from short circuits, surges, and overloads. The QLB-153-11B3N-3BA is no exception. This circuit breaker is ideal for applications in residential and commercial buildings, industrial systems, and commercial/industrial machinery and equipment.The QLB-153-11B3N-3BA is a thermal-magnetic circuit breaker designed to protect three-phase electrical systems. It has three poles, with each pole enabled with a thermal circuit breaker and a magnetic short-circuit protection. The breaker is rated for both AC and DC systems and is capable of withstanding high inrush currents.The QLB-153-11B3N-3BA is designed to protect against overloads and short circuits, ensuring that the electrical system remains safe and reliable. It has a thermal overload protection that uses heat generated by the current to trip the breaker if it exceeds a certain value. The magnetic trip will detect high current exceeding a predetermined value and trip the breaker within 60 milliseconds or less, preventing any further damage to the components of the electric system.The circuit breaker\'s contactors are protected from arcing by silver-alloy contacts which are extremely durable and provide reliable operation over a long service life. The tripping mechanism of this circuit breaker is exceptionally sensitive and will protect against all types of short circuit conditions.The QLB-153-11B3N-3BA also has an in-built indication system which allows the user to easily check the current status of the circuit breaker. An external manual operation can be used to reset the breaker after an overload has been detected. This makes it easy to restore power to the circuit in just a few seconds.In addition, the QLB-153-11B3N-3BA has a two-pole voltage monitor. This means that it will detect any voltage imbalance between two phases, and if this exceeds a preset value, then the breaker will trip, preventing any damage to the electrical components.Overall, the QLB-153-11B3N-3BA is an ideal choice for residential, commercial and industrial applications. It has thermal and magnetic short-circuit protection, advanced overload protection, and a voltage monitor. It offers superior protection in high-intensity electrical systems and ensures that they remain safe and reliable.
